Fluorine is more electronegative than either boron or phosphorous. What conclusion can be drawn from the fact that `BF_(3)` has no dipole moment but `PF_(3)` does

A

`BF_3` is not spherically symmetrical but`PF_3` is symmetrical

B

`BF_3` molecule must be linear

C

The atomic radius of P is larger than the atomic radius of B

D

The `BF_3` molecule must be planar triangular

Text Solution

Verified by Experts

The correct Answer is:
D
Due to a lone pair in P atom `PF_3` does not has a symmetrical structure.
